Supposing that you have downloaded the pages into .html files, you can simply read the file into a String with the StreamReader.ReadToEnd method, and save that in a varchar or nvarchar field.

But when the string goes to update sql code it will still have characters such as ' that will not work properly with the sql update.

currently using this code;

WebClient client = new WebClient();
byte[] webpageraw = null;
webpageraw = client.DownloadData(sURL);
System.Text.ASCIIEncoding enc = new System.Text.ASCIIEncoding();
string fullHtml = enc.GetString(webpageraw);

Open in new window


then string fullHtml is saved by SQL "update tablename set html = fullHtml "

but fails as fullhtml has characters such as ' that prevent update.

Use a parameterized query. It will take care of all the special characters.

It is the html content of a web page that is being saved into a SQL field via an update statement that is causing the problem not the URL.

A parameterized query doesn't care if what you put into the parameter is an URL, HTML, or SQL.
SqlCommand cmd = new SqlCommand("update table set column=@page", connection);
cmd.Parameters.AddWithValue("@page", html);

Open in new window
